BaseTools: Script for converting .aml to .hex

Browse Source 
The "-tc" option of the iasl compiler allows to generate a
.hex file containing a C array storing AML bytecode.

An online discussion suggested that this "-tc" option
was specific to the iasl compiler and it shouldn't be relied
on. This conversation is available at:
https://edk2.groups.io/g/devel/topic/39786201#49659

A way to address this issue is to implement a compiler
independent script that takes an AML file as input, and
generates a .hex file.

This patch implements a Python script that converts an AML
file to a .hex file, containing a C array storing AML bytecode.
This scipt has been tested with the AML output from the
following compilers supported by the EDKII implementation:
  * Intel ASL compiler
  * Microsoft ASL compiler
